How correctly override WinAPI function OleUIPasteSpecial for Microsoft Layer for Unicode
-
With help of this forum (thanks to good peaople) I learned how to use MSLU with MFC apps (http://www.trigeminal.com/usenet/usenet.asp?1033) The only thing I need to do to complete my task is to override OleUIPasteSpecialW, changing properly some members of LPOLEUIPASTESPECIALW structure, making LPOLEUIPASTESPECIALA from it and then calling OleUIPasteSpecialA. The problem is in displayng FormatName(s) in listbox. How to get them to translate from Unicode to ANSI using WideCharToMultiByte? All this required to let the OLE stuff to work correctly in MFC apps in Edit menu->Paste Special.

LPWSTR lpszMsg; [...] // First calculation of the size needed to store the converted string int iCharSize = WideCharToMultiByte(CODE_PAGE, 0, lpszMsg, -1, NULL, 0, NULL, NULL); // Alloc a ANSI string LPSTR formatANSI = (LPSTR) HeapAlloc(GetProcessHeap(), 0, sizeof(char) * iCharSize); // convert WideCharToMultiByte(CODE_PAGE, 0, lpszMsg, -1, formatANSI, iCharSize, NULL, NULL); //... // use FormatAnsi there //... // Free the ANSI string HeapFree(GetProcessHeap(), 0, formatANSI);HTH, K.
